The U.S. Chamber of Commerce filed a motion on Thursday to challenge President Barack Obama's recess appointments to the National Labor Relations Board.
The business trade group asked a U.S. Court of Appeals to add the challenge to a pre-existing case, arguing that Obama's appointments violate the Senate's constitutional right to review board candidates.
"Appointing three of five members to the NLRB in a legally questionable way casts doubt on the work of the entire agency," said Thomas Donohue, president and chief executive of the chamber.
